I need to create a simple module for user login, because the design requires a custom appearenace that the dnn login module can't do.

I set a textbox for username and another for password and a button, but I need to know how to perform the login as dnn would do, so the user gets properly logged in or show a message for wrong username / password.

Any help would be appreciated.

Thanks in advance.

Thanks. I managed to do it with some modifications to the code from the URL you posted.

In case someone needs it here it is ( the code is not complete, I still need to add a message when the login or password is wrong, etc.. ) :

 protected void lnkLogin_Click(object sender, EventArgs e)
        {
            string AuthType = "DNN";

            DotNetNuke.Security.Membership.UserLoginStatus status = new DotNetNuke.Security.Membership.UserLoginStatus();
            DotNetNuke.Entities.Users.UserInfo userInfo = DotNetNuke.Entities.Users.UserController.ValidateUser(PortalId, txtUsername.Text, txtPassword.Text, AuthType, "", PortalSettings.PortalName, DotNetNuke.Services.Authentication.AuthenticationLoginBase.GetIPAddress(), ref status);

            switch (status)
            {
                case DotNetNuke.Security.Membership.UserLoginStatus.LOGIN_SUCCESS:
                    UserInfo.Membership.Password = txtPassword.Text;
                    UserInfo.Username = txtUsername.Text;

                    DotNetNuke.Entities.Users.UserController.UserLogin(PortalId, UserInfo, PortalSettings.PortalName, DotNetNuke.Services.Authentication.AuthenticationLoginBase.GetIPAddress(), true);

                    Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(), true);
                    break;
                case DotNetNuke.Security.Membership.UserLoginStatus.LOGIN_SUPERUSER:
                    UserInfo.Membership.Password = txtPassword.Text;
                    UserInfo.Username = txtUsername.Text;

                    DotNetNuke.Entities.Users.UserController.UserLogin(PortalId, UserInfo, PortalSettings.PortalName, DotNetNuke.Services.Authentication.AuthenticationLoginBase.GetIPAddress(), true);

                    Response.Redirect(DotNetNuke.Common.Globals.NavigateURL(), true);
                    break;
                default:
                    break;
            }
        }
